Seventeen initial bituminous treatment projects were advertised for bids during 1963, which permitted bituminous concrete Class I Surface (hot-mix) as an alternate to Class C-1 Surface (road-mix). The hot-mix surface course was to contain a minimum of 6 percent PAC-9. Eleven of the contracts, totaling 38.841 miles in length, were awarded as hot-mix; and the remaining six contracts, totaling 18.12 miles in length, were awarded as road-mix

May 8, 1964 MEMORANDUM H. l. 64. 9 TO: FROM: SUBJECT: A. 0. Neiser Assistant State Highwf .E?ineer Jas. H. HavensQ ff,cJf'. Director of Resfa'r.ch Inspection Report;. Performance of Initial Surfacing Projects, Constructed During 1963; Class I, Bituminous Concrete, Containing PAC-9. Following the Research Committee meeting, April 17, 1964, at which time you expressed an urgent but timely interest in the perform-" ance of initial surfacing projects constructed during 1963, Mr. R. L. Florence, Research Engineer, made an expeditious inspection of all such projects of record and prepared the brief report which I have appended hereto as attachn1ent No. 1. This report supplements two previous re-ports pertaining to the use of PAC-9 in Class I, bituminous concrete for initial surfacing of traffic-bound macadam roads. Those two reports are appended hereto, as attachments 2 and 3, for your convenient reference. They are concerned, of course, with the Morgantown- Woodbury Road. You will recall that attachments 2 and 3 were also previously used as supplemental information in our March, 1964, research report, entitled "Base Stabilization; Initial Bituminous Treatment", which was submitted to the Research Committee at its recent meeting. 1 am sure that you will find Mr. Florence's photographs and observations to be reassuring -- that is, provided that certain ex-ceptions are admissible. Figure 17, SP26-l65, illustrates what I would consider to be an admissible exception. Perhaps, we should not ev·en expect roads of this type to withstand heavily loaded trucks without sus-taining severe, recurring damage. Also, mention is made in the report to instances where the edge-support is inadequate; but, there again, this may be an admissible exception when the type and class of road is taken into account. Weaknesses in the foundation material seem to become ex-posed in a very disturbing way; however, this seems to be the general rule rather than the exception on all light-surfacing projects which carry loads heavier than passenger cars. Memo To: A. 0, Neiser -2- May 8, 1964 I had an opportunity to inspect the Morgantown- Woodbury Road on May 7th; and, although there were several localized failures, they constituted only a very small percentage of the length of the road. Certain portions of the surface had bled somewhat, but elsewhere the surface had bleached and looked rather dry. By copy of this memorandum and the attachments hereto, I am requesting Mr. W. B. Drake, Assistant State Highway Engineer, to forward any comments which he might wish to add. Attachments cc: ·w. B. Drake May 4, 1964 MEMORANDUM TO: J, H, Havens Director of Research FROM: R, L, florence £.,.(7 Research Engineer SUBJECT: Performance of Initial Treatments, Constructed During 1963; Class I Bituminous Concrete Sur-face, Containing PAC-9, Seventeen initial bituminous treatment projects were ad-vertised for bids during 1963, which permitted bituminous concrete Class I Surface (hot-mix) as an alternate to Class C-1 Surface (road-mix}, The hot-mix surface course was to contam a minimum of 6 percent PAC~9, Eleven of the contracts, totaling 38,841 miles in length, were awarded as hot-mix; and the remaining six contracts, totaling 18,12 miles in length, were awarded as road-mix, Nine of the eleven hot-mix projects were inspected this month by personnel of "the Research Division, The two rerraining hot-mix projects were not inspected inasmuch as one, Muhlenberg County RS89-288, has not been constructed to date and the other, Fleming County SP35-160, involved considerable reconstruction and is only 0,099 miles in length, Inasmuch as three of the contracts were for a group of roads, the projects inspected were made up of seventeen roadways--totaling 35,442 miles in length, On most of the projects. the construction consisted only of priming the existing traffic-bound base with RT-2 and then lay-ing the hot-m:Lx surfacing, Ditching and shouldering was included in the contl'acts for three projects, On the Clay County project, SP26-l65, t;he contract required 1000 tons of additional base stone for reshaping and canpacting, Binder and surface mixtures were placed on Crittenden County RS28-606, At present all of the sur-faces a:re in good condition, In general the surface courses aT'e dense, appear to contain an ample amount of asphalt cement, and the centerline joints are tight, No significant amount of flushing of the asphalt cement was apparent on any of the surfaces, Only a very small amount of rutting and cracking has occurred to date, Cracking and rutting of the surface was noted on only five of the seventeen roadways inspected and in every case the cr<l.cking vJas limited to a very small peccentage of the total surface, On most of the roadways the shoulders are VE>:ry narrow, or virtually non-existent, and some cracking along the pave-ment edge, such as shown in Figure 3 attached, may be anticipated, RLF:lga Attachments Road: Width: ANDERSON COON'l'Ys RS3-9U The Leathers Road fi"CCIl RH101!9 to Ky. 1291, a distance of 2.1!00 miles, 12 feet Contract Tonnage: 11!65 Contractor: Comments: MaGo Construction ~y The overall appearance of the road was good.
