These equipment include the following: road scrapers, grain cart, and Terragator (i.e. fertilizers). All of these equipment carry heavy loads in the order of 100-200 kN per single axle. The majority of these vehicles also use lugged tires with a highly non-uniform contact area at the tire-pavement interface. In order to assess the equivalent damage that such vehicles impose on highway pavements, the SDDOT initiated a study to measure the response of field pavement sections under the loading conditions of heavy construction and agricultural equipment. The experiment measured the responses of six pavement sections in South Dakota to the loading conditions of ten combinations of vehicles and axle loads. The measured pavement responses included strains, stresses, and deflections. The analysis of field measurements of flexible pavement responses under the scraper, grain cart, and Terragators showed that most of these vehicles are more damaging than the 80-kN single axle loads. It was recommended that SDDOT limits the use of such equipment on flexible pavements to reduce their impact on the overall performance of such pavements.

Often loss of load transfer and loss of support (LOS) are hard to predict. There are several ways to evaluate them. Currently they are identified by visual evaluation and faulting measurements. Most often slab jacking, grouting, and special material treatments are applied to correct the defect. But it is hard to measure effectiveness of such treatments. Presently, nondestructive tests such as Falling Weight Deflectometer (FWD) have been used to measure deflections of pavement to evaluate loss of load transfer and support. Some of the corrected slabs resulted in lesser load transfer efficiency. Again, the FWD analysis resulted in very poor load transfer efficiency in the pavements without any visible or substantial faulting. Five different load transfer efficiency computation methods were evaluated. The FWD deflection analysis used to evaluate the maintenance treatment on the corrected slabs resulted in mixed conclusion. Methods have been used in the evaluation of rigid pavement condition survey and apply appropriate application. The load transfer in the rigid pavement without dowel bar is due to aggregate interlock and base/subbase support. A method has been devised to evaluate the load transfer efficiency (LTE) and a criterion for LOS has been selected. Statistical analysis-of-variance was used to analyze significance of the different results. The result from this method reflected the true condition of the existing pavement and is recommended for the rigid-pavement-condition evaluation. The paper discussed in detail using the Utah rigid pavement system level data.","PeriodicalId":11581,"journal":{"name":"Eleventh International Conference on the Bearing Capacity of Roads, Railways and Airfields, Volume 1","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89664995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both were surface dressed structures, one with a 20cm thick unbound base course layer and the other with the base divided into a 10cm bitumen stabilized base over 10cm unbound base. The test road structures were instrumented to estimate deflections, strains and stresses in various locations in the pavement structure. Elastic response analysis, by using a 3-D finite element (FE) technique, was carried out to simulate the tested structure and compare it with the actual measurements. The elastic stiffness moduli were entirely derived from plate load test (PLT) results. The comparison of stresses showed relatively good correlation in the subbase and the embankment. However in the base course deviation occurred between the numerical analyses and the measurements, which increased as tyre pressure increased. This was probably due to the nonlinear behaviour of the base, which was not taken into account in the linear elastic analyses. Surface deflection measurements under the wheel load on the other hand gave lower values than the numerical analyses, which it should not if nonlinear behaviour in the base took place.

Two different asphalt mixtures, straight and modified, and two different base-course materials and mechanically stabilized stone, were used in the tested pavement sections. Moreover, three different temperature conditions, immediately after construction, normal temperature and 60 degrees C, were imposed in the tests. This paper focuses and discusses on the temperature variation and displacement behavior of the asphalt pavements observed during repeated plate-loading tests. As the results, a large deflection near the loading plate took place for the temperature condition of immediately after construction; but as temperature went down, the deflection decreased near the loading plate and a bit increased away from it. This was due to an increase of the stiffness of the asphalt mixture and was indicative of that the load transmissibility of the asphalt mix layer rejuvenated with a decrease in temperature. There existed linear relationships between the surface displacement differential, d0-d10, and the average temperature of surface layer in semi-logarithmic coordinates. From these relationships, it was confirmed that the modified asphalt mixture was less sensitive to temperature than the straight asphalt mixture and that the asphalt-treated base layer also exhibited temperature sensitivity.
