Abstract
A method and material is provided for surfacing and repairing broken pavements with an elastomeric paving material comprised of the reaction product between a paving grade asphalt and a non-oil resistant rubber having petroleum malthenes admixed with said reaction product to improve the flexing properties at freezing temperatures of said paving material without any significant loss of viscosity at the high temperatures of application.
Claims9
An elastomeric paving material prepared by reacting a mixture comprised of paving grade asphalt and non-oil resistant rubber, said paving material containing a malthene in an amount of about 3 to about 20 weight percent of said asphalt-rubber-malthene mixture, whereby said paving material exhibits improved low temperature flexing properties without any significant loss of viscosity at elevated temperatures used to apply said paving material to pavement.
In a method for surfacing pavement and repairing broken pavement with an elastomeric paving material comprised of the reaction product of a mixture of paving grade asphalt and a non-oil resistant rubber, the improvement comprising the step of admixing a malthene with said asphalt-rubber reaction product in an amount of about 3 to about 20 weight percent of said asphalt-rubber-malthene mixture, whereby said paving material exhibits improved low temperature flexing properties without any significant loss of viscosity at elevated temperatures used to apply said paving material to pavement.
