COMPACTION EQUIPMENT FOR ASPHALT MIXTURES: PART 2 - PNEUMATIC TIRE ROLLERS

Analysis of the compaction effect of pneumatic tired rollers indicated that the contact pressures for a given inflation pressure and wheel loading will vary in a similar fashion to the steel wheel. Therefore, it is significant to point out that the actual contact pressure and contact area will always be less than the steel plate rating given by the tire manufacturer and will depend on the depth of penetration of the tire into the mix. It appears that pneumatic rollers and static steel wheel rollers do exert the same range of pressures. Therefore, the differences in the respective performances have to do with the shape of the contact area, the size of the contact area for a given pressure, and the difference in the macro-surface texture developed by steel versus rubber. These points are discussed in the article, along with tire size effects, variable tire inflation, performance, and others.
