Foreword
"Technical Specification for Construction of Highway Subgrades" (hereafter referred to
as simply "this Specification") is modified according to the requirements of Jiao Gong Lu Fa
[2003] No. 297 issued by the Ministry of Communications-"Notice on Printing the
Development and Revision Plan of National Engineering Construction Standards in 2003".
Based on the broad investigation and featured argumentation, this Specification
comprehensively summed up the construction experience of highway subgrades in recent
years, absorbed mature application performance of new technology, new process, new
facilities and new materials, borrowed ideas from relevant international standards (codes), and
incarnated the logos of security, economy, environmental protection and sustainable
development.
"This Specification" is consisted of 10 chapters after revision. 1. general provisions; 2.
terminologies and symbols; 3. preparation of construction; 4. general subgrade construction; 5.
subgrade drainage. 6. special subgrade construction; 7. subgrade construction of winter and
rainy season; 8. subgrade protection and supp01iingiretaining; 9. subgrade safe construction
and environmental protection; 10. subgrade renovation and work-delivery acceptance.
This revision mainly protracts the guidelines shall be observant and the technical
requirements shall be met in the subgrade construction; emphasizes process requirement of
compulsive construction, and process quality control. The primary coverage of th is revision
1s.
1. It covers construction contents of "Technical Specifications for Design and
Construction for Fly Ash Embankment" (JTJ 016-93), "Technical Specifications for Design
and Construction of Highway Embankment on Soft Ground" (JTJ 017-95) and "Technical
Specifications for Application of Geosynthetics in Highway" (JTJ 019-98).
2. It cancels light-duty compaction standard, modifies detection frequency of compaction
degree, and it also proposes dedicated compaction standard for wet clay, red clay and mezzo
piano swelling soil in the special subgrade construction.
3. This Specification abstains from a unified provision for the lay-down thickness of the
placing layer; instead, it requires the lay-down thickness combining with the process
conditions and being detennined according to the trial pavement section.
4. This revision combines the contents of "4. General rules of sub grade construction", "5"
Construction of the ea1ih-fill embankment", "6. Construction of the excavation cutting" and
"7. Subgrade compaction" in the original Specification into one "4. General subgrade
construction" .
5. It supplements subgrade construction contents of EPS block embankment construction,
subgrade widening reconstruction, breast wall, side slope anchor, brad support, friction pile,
safety and environmental protection, and also enlarges the covering scope.
All relevant organization is kindly request to sum up and accumulate your experiences in
