California City Experiments With Precracking Treatment
Engineers hope that a new type of precracking treatment will save money and improve recycling procedures over the lifetime of a one-mile stretch of asphalt roadway in La Quinta, Calif.
The city awarded San Bernardino, Calif.-based Mattich Corp. a $105,000 contract to microcrack a two-lane country road prone to large shrinkage cracks. The road will then be paved with a Full Depth Asphalt Recycling (FDAR) combination of asphalt and cement.
