Texas Uses Fabric to Protect Pavement from Cracks
Thin asphalt concrete overlays are susceptible to reflective cracking, which is the migration of the cracks in an old pavement into and subsequently through its overlay. To find a remedy...
Let's Consider Land Treatment, Not Land Disposal
The regulations that control operation and design of land treatment systems are discussed. A solution to control ground water pollution must consider all potential impacts. Pretreatment,...
Porous Friction Course Solves Airport Hydroplaning Problem
Several hydroplaning incidents had occurred at the Greensboro-High Point-Winston Salem Regional Airport, N.C. Hydroplaning occurs when hydrostatic pressure builds up in the field of surface...
Computer Cartography Offers County Unlimited Combinations and Considerable Savings
A Sacramento County pilot program to compare conventional scribed overlay mapping with computer cartography has shown that initial savings of nearly $6,000 per square mile result when...
Economics of Preventive Highway Maintenance
The preventive maintenance concept for asphaltic highway surface care is intended to give all areas of the Kansas Department of Transportation the necessary procedures for such work. The...
Runway Rebuilding with Daily Use
At Ontario the main runway was rebuilt and 4-inch bituminous overlay put down at night while the runway was in daily use. Existing pavement was portland cement concrete with bituminous...
Proposed Standards: Land Disposal of Effluents
There are many alternatives to costly advanced waste treatment (AWT) systems. The most attractive of these is land disposal of the sewage effluents from secondary treatment plants. Land...
The Floating Cover: Best Way to Cover a Finished-Water Reservoir�
With the increased attention being given to drinking-water quality in recent years, many states have been pressuring towns and cities to cover their open, finished-water reservoirs. Years...
Fly Ash Pavements, Run Ways to Take Off�
Significant cost savings were realized in paving a new container terminal storage yard in Portland, Oregon. A computer analysis showed that a multi-layer pavement would be best, with each...
