Abstract

The invention discloses a novel pitch, comprising the components according to weight portion as follows: 100 portions of pitch, 10 to 25 portions of epoxy, 10 to 25 portions of styrene-butadiene rubber, 3 to 5 portions of barite and 0.5 to 3 portions of anti-aging agent. The modified pitch of the invention has the advantages of simple production technology, easy operation and low cost, and can effectively improve the property of pitch and is suitable for roadway paving.

Description

technical field [0001] The present invention relates to a new type of asphalt. Background technique [0002] Asphalt pavements generally consist of bitumen and aggregates. Oxidation of the bituminous binder during its use, climatic conditions and use of the pavement, especially with heavy loads, lead to the degradation of the pavement over time. For example, repeated contraction of pavement due to temperature changes during cold winter nights causes vertical cracks in the pavement, known as cold fractures. The asphalt binder becomes too soft during the hot summer months, causing permanent deformation of the pavement, known as "rutting," under repeated heavy loads. In addition, as a result of the continuous mechanical stress the pavement becomes fatigued, leading to the formation of alligator-like cracks, known as fatigue fractures. [0003] However, the high wax content of asphalt makes the pavement paved with asphalt easy to soften at high temperature, resulting in stack...
