We have a job that requires Hveem stability of 37 minimum. The mix used 25% RAP and the production was on the high side of AC content (5.6% vs the 5.0% as target), the air voids dropped to around 1% and Hveem stability was only 12. The lab mix design data with around 5.6% AC shows around 30...
We have a newly constructed asphalt pavement that has a small isolated area (1ft by 3 ft) under left wheel path showed surface loss, mainly big aggregate loss. The initial thought after looking at the pictures are due to the gasoline spillage. Is there any lab tests we can use to verify this...
