NONWOVEN FABRIC FOR ASPHALTIC PAVING, METHOD FOR MANUFACTURING THE SAME, AND ASPHALTIC PAVING METHOD

摘要

PURPOSE: A method for fabricating a non-woven fabric for anti-cracking of asphalt pavement is provided to effectively prevent cracking of asphalt and to enhance durabilitiy of asphalt pavement. CONSTITUTION: A method for fabricating a non-woven fabric for anti-cracking comprises: a step of preparing a fiber of bundle type twisted with polypropylene fibers and aramid fibers(S11); a step of mixing fiber glass with the fibers of bundle type(S12); and a step of adding adhesive to a mixture containing fiber glass and performing pressed thermal treatment to prepare a fiber of non-woven fabric. [Reference numerals] (S11) Fabricating a bundle type fiber which is finely twisted(polypropylene fiber + aramid fiber); (S12) Mixing fiber glass to fiber of bundle type(polypropylene fiber + aramid fiber + fiber glass mixture); (S13) Adding adhesive; (S14) Fabricating fiber of non-woven fabric by extruding and thermal treatment
