mixed traffic the total E80s is the number of 80 kN axle loads which causes the same damage as the actual spectrum of axle loads imposed. The 80 kN standard

Some ESAL; Equivalent Single Axle Loads ¾One of the main deliverables of the AASHO Roads Test 1958 – 1960 ¾A method of aggregating all traffic loads into their equivalent number of standard single axle loads. Single axle 18 000 lbs (18 kips) axle load Dual tyre ¾Widely used in many countries for many years ¾LEF: Load Equivalency Factor The average axle load spectrum of Yanjing highway in recent five years was obtained from the pavement management system (PMS) in Jiangsu Province, China. Four common axle–wheel groups, like single-axle single-wheel, single-axle double-wheel, double-axle double-wheel, and three-axle double-wheel groups, could all be converted into the single Based on the survey of the vehicle flow, vehicle model, total gravity and axle load of the Jiangyin Yangtze River Highway Bridge within a month, a large amount of data are obtained. Then the fatigue-loaded vehicle model and load frequency spectrum and axle-loads distribution is derived.

Axle load spectrum

Therefore, some load amplitudes higher than ones measured in the test can occur during a long-term axle service. The contribution presented deals with the effect of Standard Load Equivalencies Type of Axle or Axle Group Loading Equivalent to One ESAL (kips) single tire single axle 12 dual tire axle 18 tandem axle group 32 tridem axle group 48 4 or more axle group 48 An axle is considered part of an axle group when it is less than 8 feet from another axle or group. 2009-08-03 Variations in the dynamic tire forces of commercial freight vehicles, known to accelerate the road damage, are strongly related to vibration modes of the vehicle associated with vertical and pitch motions of the sprung and unsprung masses. The high levels of tire induced road damage caused by heavy vehicles has prompted a growing demand for the design of road-friendly vehicles. Load spectrum is a basis in cartying out fatigue-strength test and service life calculation oftypical components in farm machinery.In order to evaluate fatigue feature of typical components,this paper has analysed the road load-time history of the rear-axle and the steering frame of aside tipping agri-t(?)ailer,model 7cc-5 by adopting peak value counting technique,ie,taking thefrequency in Wczytywanie gry w czasie rzeczywistym do komputerka ośmiobitowego Timex 2048 klon ZX Spectrum.

A 133.3 kN (30,000 lbs) single axle does about 67 times more damage than a 44.4 kN (10,000 lbs) single axle (7.9/0.118 ˜ 67). A 133.3 kN (30,000 lb) single axle does about 11 times more damage than a 133.3 kN (30,000 lb) tandem axle (7.9/0.703 ˜ 11). Heavy trucks and buses are responsible for a majority of pavement damage.

8. Size of load as a percentage of maximum permitted load. 9. The most commonly used equivalent load in the U.S. is the 80 kN (18,000 lbs) equivalent single axle load (normally designated ESAL).

Design ESALs is a cumulative traffic load summary statistic. The statistic represents a mixed stream of traffic of different axle loads and axle configurations pavement, it undergoes traffic loads of various axle. Mehran University standard axle load for a truck traffic mix incorporating multifarious axle load spectra. 21 May 2015 How to account for this ? Response : Use the factor Cd/I as an additional multiplier for the seismic load in the combinations that are The axle load of a wheeled vehicle is the total weight bearing on the roadway for all wheels connected to a given axle.

Therefore, some load amplitudes higher than ones measured in the test can occur during a long-term axle service. The contribution presented deals with the effect of 24 Oct 2012 under National Cooperative Highway Research Program Project 1-37A requires the use of axle load spectra or load distribution factor for estimating axle load spectra for all years the LTPP sites were in service. Phase 2 used this methodology to estimate axle loads for all LTPP sites that had 19 Dec 2014 Processing axle load data provided the number of axles per truck and axle load spectra for each of the traditional 13 vehicle classes.
