Abstract
The invention discloses an environment-friendly pressure-proof road paving material. The material comprises the following substances by weight: 100 to 150 parts of broken stone, 12 to 15 parts of diatomite, 5 to 9 parts of meerschaum, 3 to 5 parts of diatomite (80 to 180 meshes), 2 to 4 parts of opened-cell expanded perlite, 2 to 7 parts of hollow glass beads (120 to 200 meshes), 10 to 26 parts of acetylacetonate, 3 to 9 parts of ethyl silicate, 4 to 9 parts of methyltrimethoxysilane, 1 to 8 parts of poly(4-methyl-1-pentene), 6 to 10 parts of active calcium, 5 to 8 parts of stearic acid and 10 to 15 parts of a filling material. The invention has the following beneficial effects: better construction workability is obtained, time for traffic opening is shorter, effective compaction time is longer, so road construction quality is improved.
Description
Technical field
The present invention relates to the withstand voltage road pavement material of a kind of environmental protection.
Background technology
At present, China to have in paved road engineering what more than 90% adopt be the road surface of asphalt making.Bituminous pavement compare with cement pavement there is excellent road performance, easy to maintenance, driving noise is little, construction costs is low etc. advantage.But in construction and use procedure, existing asphalt exists following not enough: 1, under the condition of high temperature, construction easily causes ageing of asphalt, because traditional basis bitumen and modified bitumen viscosity under the condition of high temperature is large, high like this construction temperature is very easy to cause the aging of pitch, thereby affect long-term behaviour and the work-ing life of bituminous pavement, to such an extent as to early disease takes place frequently, this is also to cause the common people to complain, a major cause of the road routine maintenance problem of government's headache.2, the time limit of annual suitable construction shorter, be to guarantee homogeneity and the compactibility of asphalt, bituminous pavement paving temperature should be not less than 125 degrees Celsius, grinds because compound heat radiation is too fast, easily causes compactness not enough.China most areas asphalt pavement construction cycle mainly concentrates on the first tenday period of a month in May to mid or late September.Owing to forbidding that the time limit of construction is longer, had a strong impact on the process of Road construction and maintenance and renovation, also cause construction machinery and personnel's the huge waste of idle generation.Meanwhile, many engineerings, in order to work to tight deadlines, comprise some special engineerings, and the time is rolled on road surface and temperature can not be guaranteed, and cause the construction qualities such as compactness deficiency often to occur, directly affect using character and the work-ing life on road surface.Problems is particularly outstanding at northern China wide geographic area.3, in asphalt road surface construction process, contaminate environment bituminous pavement, in paving process, need to mix and stir, pave, roll under the condition of high temperature, therefore can give off the poisonous and hazardous pollutents such as a large amount of CO2, S02, and a burst of phenomenon of glance coal is seen everywhere.Especially when blending station storage bin is put into transport trolley by compound, the phenomenon of Mao Qingyan is obvious especially.The glance coal producing in construction process, benzo just etc. volatile matter to workmen and around the common people's health also form great threat, affect the living environment of working-yard surrounding resident.
Summary of the invention
Technical problem to be solved by this invention is to provide the withstand voltage road pavement material of a kind of environmental protection.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
The road pavement material that a kind of environmental protection is withstand voltage, it is characterized in that, the material that comprises following parts by weight: rubble 100-150 part, diatomite 12-15 part, sepiolite 5-9 part, diatomite (80-180 order) 3-5 part, perforate pearlstone (14-120 order) 2-4 part, hollow glass micropearl (120-200 order) 2-7 part, acetylacetonate 10-26 part, modified aqueous acrylic acid resin 11-13 part, tetraethyl silicate part 3-9, methyltrimethoxy silane 4-9 part, poly--4-methyl-1-pentene 1-8 part, Calcium of intensifiens 6-10 part, stearic acid 5-8 part, filler 10-15 part, film coalescence aid 14-25 part, solubility promoter 4-9 part.
The invention has the beneficial effects as follows: there is better construction working, shorter open to traffic and longer time available for compaction, thus improve Road construction quality.
