purchased or crushed, is it not wise to invest a few hundred dollars in testing the material to insure that the right aggregate is used? It is a good practice to test the aggregate before placing it on the road.Also, if the tests fail, you can work with the crushing contractor to try to blend and improve or reject the material. This becomes ...
