**************************************************************************
A cross polymer resin of styrene and butadiene, Prosalvia L7, shall be
utilized as a plasticizing and strength producing agent. After mixing the
resin into the slurry grout, the mixture shall have a viscosity which would
allow it to flow from a Marsh Cone in accordance with Table III. A Marsh
cone has dimensions of 155 mm 6-1/8 inches base inside diameter, tapering
315 mm 12-3/8 inches to a tip inside diameter of 10 mm 3/8 inches. The 10
mm 3/8 inch diameter neck shall have a length of 60 mm 2-3/8 inches.

JOB MIX FORMULA FOR OPEN-GRADED ASPHALT AND SLURRY GROUT
**************************************************************************
NOTE: It is recommended that the job mix formula
for the open graded bituminous mixture and the
by the appropriate ERDC representative. On a case
by case basis, this approval may result from a
simple review of the Contractor's mix design test
reports, or it may require verification of the mix
design by repeating some or all of the required mix
design tests. This recommendation is to ensure that
mix designs for this new paving process.
A complete description of the proper methods used to
produce job mix formulas for the open graded
bituminous mixture and slurry grout is found in ETL
1110-1-177 "Use of Resin Modified Pavement (RMP)."

will be made for mixtures produced prior to the approval of the JMF by the
Contracting Officer.
2.6.1.1
Initial Laboratory Procedure
(1) Sample aggregates according to ASTM D 75 and asphalt cement
according to ASTM D 140. An open-graded asphalt concrete mix
design requires a minimum of 45 kg 100lbs of each aggregate
