The reconstruction of Dillon Road consisted of the removal of approximately one-quarter mile of the existing roadway asphalt and baserock section, and preparation of the subgrade soils to receive the new pavement section, between Vista Del Norte and Avenue 44. Earth Systems performed the initial evaluation and investigation to measure the existing pavement section, obtain samples, and prepared a written report addressing site soil conditions, drainage, and providing design criteria for the replacement paving section. Earth Systems work during construction consisted of field density testing of the native soil/subgrade, aggregate baserock, and asphalt. Laboratory testing consisted of R-value testing, compaction curves, and gradation/extraction.
