Concrete and asphalt's environmental impact could be reduced by over a third through changes to manufacturing processes and the use of alternative raw materials, according to research. A scenario study based on life cycle analysis has indicated that using alternative types of cement in concrete and producing asphalt at lower temperatures could substantially improve the green credentials of these two common building materials.

The new PelletPAVE |TR is a specifically formulated PG 64 -22 binder with 12% - 15% of a very fine crumb rubber (SBR) used to enhance the performance of dense graded hot mix asphalt.

Avid readers of local history are usually intrigued by photos of historic sites juxtaposed against contemporary images. This format of visual history has a particularly strong impact when the subject is Los Angeles: a city that grew up -- and outward -- so quickly.

Those seeking pictorial overviews will likely have checked out aerial photography books as well.

Los Angeles From The Air: Then And Now (San Diego: Thunder Bay Press, 2010) is a hybrid of these two types of pictorial books. It presents decades-old photographs of both familiar and lesser-known landmarks along side more current ones.

This takes the reader on a trip through Los Angeles like never before, featuring inspiring, sky-high then-and-now images of some of LA's most famous locations.

Some of the landmarks' origins are well-known, but the authors provide context for both familiar and hidden pieces of Los Angeles history.

Many of the photos feature snow-capped peaks in the distance -- a testament to our clear Winter days being the best for photography.

Unfortunately, the work falls flat in its description of transportation in downtown Los Angeles. The authors write:

"Metrolink [sic] provides service to Union Station in the form of three rail lines -- Red, Purple, Gold..."

While Metro and Metrolink may sound similar to those outside of Los Angeles (the book is, after all, published in San Diego), it gives one pause that other information found here may not be entirely accurate. Ultimately, one can ignore the text entirely, as these beautiful photos speak for themselves.

In Makeshift Metropolis: Ideas About Cities (New York: Scribner, 2010), noted architecture writer Witold Rybczynski offers a glimpse of an urban future that might very well serve as a template for cities around the world.

Rybczynski integrates history and prediction of the development of the American city in a brisk look back that takes us from colonial town planning to the Garden City and City Beautiful initiatives of the early 20th century and on to the "Big Box Era."

He also examines how contemporary urban designers and planners are revisiting and refreshing older urban ideas, such as bringing gardens to a blighted Brooklyn waterfront.

Rybczynski's study is kept relevant by his focus on what the past can teach us about creating the "cities we want" and "cities we need."

The prose is instructive and always engaging, and the author's enthusiasm for the future of cities and his enduring love of urban settings of all kinds is evident.

He not only writes about what people want from their cities, he inspires the reader to imagine the possibilities.

In Down The Asphalt Path: The Automobile And The American City, author Clay McShane examines the uniquely American relationship between "automobility" and urbanization.

Writing at the cutting edge of urban and technological history, he depicts how new technology, namely the private automobile, and the modernization of the American city redefined each other.

The author motors us across the country -- from Boston to New York, from Milwaukee to Los Angeles and the suburbs in between -- chronicling the urban embrace of the automobile.

The New York Times calls this work "A treat to read, loaded with interesting facts...a notable book about urban transportation."

Barron's wrote that "this fascinating, well-researched history of the automobile industry...is written from a social and cultural perspective rarely included in traditional books about the business."

The Whole Earth Review claims "this fascinating treatise is the most credible look yet at how automobiles have changed American society for better or worse."

Everyone is calling for smart growth...but what exactly is it?

In The Smart Growth Manual (New York: McGraw-Hill Professional, 2009), two leading city planners provide a thorough answer. From the expanse of the metropolis to the detail of the window box, they address the pressing challenges of urban development with easy-to-follow advice and broad array of best practices.

With their landmark book Suburban Nation, Andres Duany and Jeff Speck "set forth more clearly than anyone has done in our time the elements of good town planning" (The New Yorker).

In this long-awaited companion volume, the authors have organized the latest contributions of new urbanism, green design, and healthy communities into a comprehensive handbook, fully illustrated with the built work of the nation's leading practitioners.

This work also features a valuable Smart Growth Directory, with contact information for national, regional and state organizations.

Lieutenant Governor-Elect Gavin Newsom, writing as Mayor of San Francisco, touted The Smart Growth Manual as "an indispensable guide to city planning. This kind of progressive development is the only way to full restore our economic strength and create new jobs, new industries, and a renewed ability to compete in the first rank of world economies."

An extensive interview with the authors is featured on the American Society of Landscape Architects "The Dirt" blog.

The conventional wisdom says that we need strict planning to build walkable neighborhoods around transit stations - even though these neighborhoods are like the streetcar suburbs that were common in America before anyone heard of city planning.

In reality, many of our greatest successes in urban design have occurred when we treated the issues as political questions - not as technical problems that the planners should solve for us.

According to Unplanning: Livable Cities And Political Choices (Berkeley, Calif.: Preservation Institute, 2010), the anti-freeway movement of the 1960s and 1970s and the anti-sprawl movement of recent decades were both political movements, and citizen-activists often had to work against projects that planners proposed and approved.

This book uses an intriguing thought experiment to show that, in order to build livable cities, we should go further than the anti-freeway and anti-sprawl movements by putting direct political limits on urban growth.

Political choices about how we want to live can transform our cities more effectively than planning.

From animal paths to superhighways, transportation has been the backbone of American expansion and growth.

Asphalt And Politics: A History Of The American Highway System (New York: McFarland, 2009) examines the interstate highway system in the United States, and the forces that shaped it, includes the introduction of the automobile, the Good Roads Movement, and the Lincoln Highway Association.

The book offers an analysis of state and federal road funding, modern road-building options, and the successes and failures of the current highway system.

A system for measuring the height of paving material distributed by an auger of a paving machine in front of a grading implement, such as a screed, is disclosed. The system includes a sonic sensor and a laser pointer. The sonic sensor generates a sonic signal which is directed at the paving material distributed by the auger. The laser pointer generates a laser beam which is similarly directed at the paving material that has been distributed by the auger. The laser beam and the sonic signal meet at a common position on the paving material.

A method of repairing cracks in a paved surface includes identifying at least one crack in the surface that needs to be repaired. The crack is then filled with an asphalt sealer including approximately 40-55% by weight of slag sand.

The present invention provides a system and method for controlling an asphalt repair apparatus. An additional aspect of the present invention is to provide a system that may position a heater repair element adjacent a targeted asphalt surface, acquire and analyze surface and heater sensing data, and control heater output to prepare the targeted asphalt surface for repair. Further, the system may be configured to control an asphalt repair apparatus to satisfy user-defined asphalt repair requirements.

In a method of milling asphalt, a relative elevation of an unmilled asphalt pavement surface adjacent to an area to be milled is sensed with respect to a milling machine body and rotatable milling drum of the milling machine. An elevation of a bottom surface of the rotatable milling drum is determined using a computer processor. Based on a map, stored in a computer memory, of a design surface specifying a design elevation of a milled surface over the area to be milled, the elevation of the milling machine body and the rotatable milling drum are automatically adjusted such that the rotatable milling drum mills the asphalt surface to the design elevation over the area to be milled.

A system and process for integrated desulfurizing, desalting and deasphalting of hydrocarbon feedstocks is provided. A hydrocarbon feedstock, a water soluble oxidant, and a water soluble catalyst can be introduced in a oxidation zone and retained for a period of time sufficient to achieve the desired degree of desulfurization, or introduced directly into the desalting zone along with wash water. Catalyst and dissolved salt are discharged along with the wastewater effluent from the desalting zone. A hydrocarbon stream including converted hydrocarbons and oxidation by-products is passed to a deasphalting zone. In the deasphalting zone, phase separation occurs, whereby a light phase including desulfurized hydrocarbons are produced, and a heavy phase including asphaltenes and oxidation by-products are discharged, e.g., passed to an asphalt pool.

(Supreme Court of California) - In a government contracts dispute alleging the tort of intentional interference with prospective economic advantage, the Court of Appeals judgment overturning the trial court's judgment sustaining defendants demurrer, is reversed where plaintiffs' allegations -- that they had submitted the second lowest bids on several contracts awarded to defendant, and that their bids would have been accepted but for defendant's wrongful conduct during the bidding process -- are insufficient because: 1) public works contracts are a unique species of commercial dealings; 2) in the contracts at issue here, the public entities retained broad discretion to reject all bids; 3) the bids were sealed, and there were no postsubmission negotiations; 4) in awarding the contracts, the public entities could give no preference to any bidder based on past dealings, and were required to accept the lowest responsible bid; and 5) in these highly regulated circumstances, plaintiffs had 'at most a hope for an economic relationship and a desire for future benefit.'
