For over 30 years, the ACPA "Excellence in Concrete Pavement" awards have honored quality concrete pavements constructed in the United States and Canada. The awards program encourages high-quality workmanship in every concrete pavement project and serves as a forum for sharing information about highly successful projects.
Many diesel-hydraulic impact crushers struggle with crushing asphalt continuously because of asphalt dust building up inside the radiators leading to overheating issues and loss of power. Diesel-electric crushers require less cooling and get away with smaller radiators, so that you face less maintenance and downtime.
Tire consumption increased exponentially due to the rapid population growth and transportation development. For reusing waste tires in concrete, all available studies turned rubber into particles, replacing concrete cement or natural aggregates. This approach, however, prevents the optimum utilization of rubber properties and decreases …

Existing pavement crack repair methods depend upon the type and severity of cracks. Badly cracked pavement sections, especially those with pattern cracking (e.g., fatigue cracking) must be patched or replaced because these distresses are often symptoms of more extensive pavement or subgrade structural failure (TRB, 2000 [2]).

Concrete Pavement Sub-Base. Concrete pavement sub-base is a layer that protects the soil. The layer compacts and protects the soil so that it isn't damaged. The material that is laid over the soil, and is used for the sub-base, is aggregate. The reason why pavement must have a sub-base is because a vehicle's weight needs strong support.
