Abstract
The paper minutely elucidates the advantages of high modulus asphalt concrete and the action mechanism of additive.Through production process there are determined all the production targets for instance the mineral aggregate grading of high modulus asphalt concrete,the proportioning of additive,the mixing temp as well as the spreading temp etc.As a result,the high modulus asphalt concrete has been produced,making the rut-resistance of asphalt pavement at high temp strengthen greatly.
