GMU is currently providing slurry seal testing and inspection for the City of Rancho Santa Margarita – Annual Residential Slurry Seal project. This project involves cracks repairs and application of a slurry seal to selected City streets. Interior residential streets were treated with a Type 1 Rubberized Polymer Modified Slurry (RPMS), while streets with more traffic were treated with a Type II Emulsion Aggregate Slurry. Slurry seals improve the surface appearance of the streets and act as a protective membrane to shield the pavement surface from sunlight and moisture, thereby reducing oxidation, weathering, and aging of the pavement. By applying the slurry seal, the City will extend the life of their streets and reduce their overall pavement costs.
GMU is performing inspection and sampling of the slurry seal for laboratory tests, such as gradation, sieve analysis, wet track abrasion, moisture content, and residual binder content. The results are evaluated for conformance with the project specifications. Our services help the City reduce risk and improve the quality of the materials used and the workmanship performed.
