Man Hole Cover Lifters

Proteus has been the market leader in providing mechanical and hydraulic manhole cover lifters for the last 20 years, and we can use our experience in the field to provide solutions to all your manhole lifting problems.Lifting manhole covers isn’t as easy as you’d expect, due in part to the vast array of different keyholes available on different types of cover, and differing sizes of covers coupled with awkward locations.

Backcalculation Validation Through Field Instrumentation

The moduli of each layer were backcalculated using several approaches. The response of the instruments to the FWD loading was recorded together with the moisture content of the granular layers and the temperature of the hot-mix-asphalt (HMA) layers.


Designed for measuring axial displacements in the simple performance tests prescribed by NCHRP Report 465, and determining dynamic modulus of hot mix asphalt per AASHTO TP062. Gauge length from 70 to 100 mm; Strain gages technology

Laboratory evaluation of moisture susceptibility of foamed warm mix asphalt

Warm Mix Asphalt (WMA) is a step in that direction. WMA allows the producers of asphalt pavement material to lower the temperatures at which the material is mixed and placed on the road. WMA is mixed and compacted at 50–100 F lower than traditional hot.

Investigating the resistance of asphaltite containing hot mix asphalt

In this study, the aim was to determine the influence of asphaltite addition on the stiffness of the hot mix asphalts as well as on their resistance against fatigue and permanent deformation through cyclic tests. The asphaltite was included as filler into the hot mix ...

Pavement Sensors

High Temperature, Dynamic Asphalt Strain Gage Jewell Instruments offers a Dynamic Asphalt Strain Gage (ASG), an embeddable strain gage designed for use in high frequency (dynamic) environments. This rugged gage is built to withstand high temperature and vibratory roller compaction, making it ideal for infrastructure and construction type projects.

Sensor Design and Layout for Airport Asphalt Pavement

5. Strain Gage Responses . Figure 8 shows strain responses for transverse gages for the bonded and delaminated cases, while Figure 9 does the same for longitudinal gages. Transverse gages are affected by lateral wheel traffic, while the LSGs are not so influenced. This is because the gages only register strains along their longer axis.

Smart Geosynthetics For Strain Measurements In Asphalt

13 validate new smart geosynthetics for strain measurements. 14 The pavement was composed of two layers: a 8-cm thick Hot Mix Asphalt (HMA) base 15 layer and a 5-cm thick surface layer. Sensors were located at the base layer/platform interface 16 and base layer/surface layer interface.

Fiber-Optic Sensor Strain Measurements Under Asphalt Layer

Fiber-Optic Sensor Strain Measurements Under Asphalt Layer During and After Construction. This project shows that Fiber-Optic Sensor Strain (FOSS) can be installed in Hot Mix Asphalt (HMA) and used to measure strains in the pavement under different types of loadings.

How much does density matter?

The normal target in-place density on a “dense” hot-mix asphalt pavement is 92 to 93 percent of Gmm (or 7 to 8 percent air voids). If a pavement has low density (usually defined as less than 92 percent of Gmm), the air voids are interconnected and premature pavement distresses can result.

obtained from two asphalt suppliers were tested to link laboratory measured properties to mix performance. Based on the results of this analysis, it is concluded that survivability and repeatability of the gages were acceptable in past experiments. However, strain gages were not a reliable indicator of damage development in hot-mix asphalt (HMA).
