Analysis on the Influence of Key Production Process Parameters of Cold-mixed Epoxy Gussasphalt Mixtures
In order to explore the construction process parameters of cold-mixed epoxy gussasphalt mixture,the fluidity,strength and crack resistance of the mixture under different mixing temperature and time,different health temperature,and different moisture content conditions were tested to determine the control parameter of key production process of cold-mixed epoxy gussasphalt mixture.The results show that:1)With the increase of mixing time and mixing temperature,the compressive strength of the mixture increases linearly,and the optimal fluidity is obtained when mixing for 10 min.Considering paving process,the mixing time should be controlled within 10 min～30 min;2)When the mixing temperature was increased by 7℃,the compressive strength of the mixture was increased by 23.6%.High temperature also lead to acceleration of curing rate of material and a shortening of construction operational time;3)With the increase of temperature,the health maintenance time is greatly shortened,and the construction operational time.When the temperature is 25℃,the terminal strength can be obtained after 10 h;4)The effect of moisture content of the coarse aggregate on the performance of the mixture is large.Considering the fluidity,strength and crack resistance,etc.,the moisture content of the coarse aggregate should be controlled within 0.5%.
