Emulsified asphalt cement stabilized macadam
The invention belongs to the technical field of road building materials and discloses emulsified asphalt cement stabilized macadam. The emulsified asphalt cement stabilized macadam is prepared from, by the weight ratio to macadam, 2-4 parts of mixed emulsified asphalt, 3.5-5.5 parts of mixed cement, 4.5-6.0 parts of water and 100 parts of macadam. The emulsified asphalt cement stabilized macadam has a hardness and softness feature and good water-damage-resistant performance, compared with common cement stabilized macadam, compression resistance and splitting strength of mixed materials are lowered, and flexural-tensile strength is approximate at the normal temperature of 20 DEG C and obviously improved at the low temperature of 5 DEG C. The dry shrinkage water-loss rate, dry shrinkage coefficient and dynamic modulus are lowered, and the limit strain capacity is increased; construction performance is excellent; compaction is easy, little segregation is generated, strength variability is small, and bad influences of delay forming and dry maintenance are weakened; the requirements for mechanical strength of pavement bases of high-grade highways and urban roads can be met, and base shrinkage cracks can be effectively reduced or prevented.
