[PL] Lenkijos keliai. Vykdomi projektai

[pzlotnik]

Expressway Poznań - Gniezno is being built in Wielkopolska Region. Some Facts:

Wielkopolska Region:

Area - 29 826 square km
Population - 3 403 174

Lithuania:

Area - 62 200 square km
Population - 3 322 200

So we have much bigger problems with private property when building roads. When I was driving through Lithuania there are huge emty spaces, in Poland we have w lot of small town and villages so sometimes there is no space to build new road.

The biggest problems with land there are in Śląskie Region in southern Poland:

Area - 12 333 square km
Population - 4 654 115.

Ar pas lenkus nėra problemų su privačia nuosavybe ar kaip čia išeina?

These pictures are music to my eyes! Beautiful stuff.

Massive road works. Great, that Poland roads infrastructure keep going into positive direction.

Yes, makes sense. I just wonder how about ride comfort? Concrete is much harder and therefore tyre noise is much more noticeable (especially in smaller cars). Or is there some technology that helps to avoid that?

Try Vienna bypass after alternation. It`s made of concrete and comfort is very good. When concrete is plain and well laid there`s no problem with noise and comfort. But older concrete technologies were of course not so good.

[pzlotnik]

Why are they choosing concrete? I thought tarmac is the option in most new highways? Or are there any advantages?

Concrete is much more permanent pavement than tarmac. First alternation is needed after 20 - 30 years of use.

Most modern highways in Germany or Austria are of concrete. Lately opened A4 section in Poland to German border - Krzyżowa is from concrete:





How it looks on A2 highway (test concrete section is ready):










It`s very modern german technology:

Section of the test is performed to verify the technology, machines and procedures for receiving, in practice, or on site. Laying of concrete pavement is working "band" and will continue for the next three days, ie until 22 November 2009. This type of concrete section is laid for the first time in Poland in the new technology that is "concrete pavement with exposed aggregate" so-called "washbeton. This technology was developed several years ago and is now used in countries such as Belgium, Austria and Germany, where since 2007 is the standard technology for concrete pavements for highways. Works are performed by Heilit & Woerner, STRABAG, which has more than 29 years experience in concrete pavements, including 16 years in Poland.

Before you start laying the concrete slab, has been previously arranged and attached geotextile which acts as a separating layer and dehydration. The construction of pavement base course consists of a thick. Of 20 cm of lean concrete, under a layer of lean concrete base course made Frost a layer thickness. 32 cm.
Positioned today surface of the concrete slab consists of 23 cm bottom layer of concrete and 5 cm top layer of concrete. Both layers are designed so that together they can cope with the enormous movement of cars projected to pressure of 115 kN / axle for more than 30 years.

"By construction, the company A2Strada (Kulczyk Holding Strabag), zdecydowałsię the implementation of the test right now because of the possible opportunity to refine the technology chosen for this year, before the start of full construction season in the spring of 2010" - explains CEO Andrew AWSAII Patalas.

That part of A2 Highway section from Nowy Tomyśl to German Border (lenght 106 km) will be finished to november 2011 and will have concrete surface, like many german highways.
By june 2012 A2 will be ready from german border to Warsaw (exactly to Minsk Mazowiecki, east to Warsaw), total lenght of 472 km.

Kas per kvailas klausimas Lenkai ir savų darbininkų, inžinierių turi.

Kiek zinau, tai Kauno tiltai su TILTRA Group ten varo pilnu tempu.

[trilobitas]

Įspūdingi darbų mąstai ....

[groundzer]

Lietuviai tuos kelius stato?

Yra rašyta, kad ties Grigiškėmis automobilių vidutinis paros srautas siekia 34000, vasarą - dar daugiau. Dar vienas faktorius - priemesčio zonose yra daug lėtaeigio transporto, daug staigesnių nuvažiavimų, lėtinančių greitį ir visą srautą. Miškuose visai pakaktų ir 2X2.

[Meier]

Lietuvoje 3+3 jau dabar reiktų A1 ir galbūt A2 atkarpose likus keliems/keliolika km iki Vilniaus, nes pakankamai dažnai auto srautas ima smarkiai lėtėti nuo mašinų skaičiaus.

D.Britanijoje norma yra 3+3 kelias su 100k AADT. Pas mus Vilnius-Kaunas yra 20k AADT. Ar tikrai reiktų 3+3? Grubiai viena juosta aptarnauja 20k AADT, antra suteikia žymiai didesnį pralaidumą. Bet ar tikrai turint 20k AADT galima kalbėti apie 3+3? Man atrodo tai tik užgaida ir noras turėti taip pat, kaip "ten vakaruose". Žinau, kad skambu nepopuliariai, nes visi čia mėgsta plačius, tiesius ir lygius greitkelius su kuo daugiau juostų ir kuo daugiau lygių turinčius susikirtimus

[groundzer]

Galų gale, vertinti reikia kelius pagal AADT prizmę - niekada Lietuvoje nebus 3+3 kelio iš Vilniaus į Augustavą, ir juo greičiau mes tai suprasime, juo lengviau visiems bus

Niekada nesakyk niekada. Gal po keliasdešimties metų mašinų (ypač krovininių) srautas ims ir padidės. Tada, be 3x3 kelių niekaip neišsiversim. Šiuo klausimu niekas negali būti šimtų procentu įsitikinęs.
