We are defining LSM as having a gradation of 100% passing the 3"-sieve, <SO% passing the 1"-sieve. and 2-5% passing the No. 200-sieve. The binder must be asphaltic. List gradations of aggregates that have been "designed in the laboratory or developed by "experience".
For laboratory mixing of aggregate and asphaltic b~nder, what was:
a) Weight of batch (g or Ib) b) Make of mixer c) Capacity of mixing bowl (volumetric) d Type of mixing beater (flex. or rigid)
4. : For laboratory compaction of specimens, what was:
a) Size of specimen diam. in. and ht. in. b) Type of compactor c) Compactive effort ft-lb./cu.in. or describe in words or reference.
d) Range of air voids desired based on Rice MTSG O h
5. For laboratory testing of specimens, what was: a) For stability- method and minimum value required. b) For durability- method and minimum value required.
Feel free to comment on the information requested and to add other information you feel would contribute to the objectives of a laboratory design1 method for large stone mixtures.
