Attached are three copies each of two laboratory reports covering tests on a 50 lb. sample of processed Kentucky rock asphalt forwarded to our laboratory by Mr. C. H. McKinney. The sample arrived June 6. These reports include results of laboratory analysis and evaluation tests - and small scale road tests - to determine the proper amount of tar to be added to the processed material to produce a satisfactory road surfacing mixture
